Hi Folks, I think I'm just about to get a 5500SHAC, but there is one thing I've not been able to confirm at the moment. What lua libraries are shipped with the device? I can see from the manuals that serial and luamodbus are definitely accessible. I can also see from Damaxx's excellent post that socket and socket.http seem to either be included or worked when uploaded as user libraries possibly. See [URL]https://www.cbusforums.com/threads/lua-script-examples.9011/[/URL]. I'm wondering if someone from the product team or someone with a device is able to help me understand: (a) what libraries ship on the device and (b) are there any significant limits on the libraries that could be uploaded as user libraries The use case I'm most interested in at the moment is talking to Haiku ceiling fans that have a SenseMe module as per the following: [URL]https://www.haikuhome.com/au/senseme[/URL] I want to get the controller to talk to the SemseMe units so I can control the fans from C-Bus as opposed to having to have yet another switch on the wall in the room for the fan. The protocol is pretty simple and has been reverse engineered by others as described here: [URL]https://bruce.pennypacker.org/2015/07/17/hacking-bigass-fans-with-senseme/[/URL] [URL]https://github.com/sean9keenan/BigAssFansAPI[/URL] [URL]https://github.com/TomFaulkner/SenseMe[/URL] So all that is needed is pretty simple UDP comms. Damaxx's examples shows setting up listening sockets etc... so I'm pretty sure this should all be fine, but I'm keen to know how far I could push one of these controllers.... If I can get it all working I'll share the code back to this forum. Then the next thing to think about is the best way to talk Z-Wave. There are a few options on that front... Cheers, Kelvin
